* CAUTION: We recommend that you use the dropper or dosage cup that comes with your medicine to avoid overdosage. Dosage recommendations on bottles may vary from the recommendation on these pages. We would like you to use our recommended dosages unless your health care provider has given you a different dosage. Aspirin should not be given to your child.

Call today to book your child's yearly well exam. If your child needs any forms filled out for sports, camp or college, our physicians can only do so if your child has had a well visit within the past twelve months.
